4、by laboratories previouslycalibrated by the TMC.In general,the Test Purchaser decides if a calibrated test stand is to be used.Organizations such astheAmerican Chemistry Council require that a laboratory utilize the TMC services as part of their testregistration process.In addition,the American Petr
5、oleum Institute and the Gear Lubricant ReviewCommittee of the Lubricant Review Institute(SAE International)require that a laboratory use theTMC services in seeking qualification of oils against their specifications.The advantage of using the TMC services to calibrate test stands is that the test lab
6、oratory(andhence the Test Purchaser)has an assurance that the test stand was operating at the proper level of testseverity.It should also be borne in mind that results obtained in a non-calibrated test stand may notbe the same as those obtained in a test stand participating in the ASTM TMC services
